VAGINAL SYRHNGE..

` SPECIFICATION forming part of Letters Patent No. 662,340, dated November 20, 1900.

Application filed December l5, 1899. Serial No. 740,44r3. (No model.)

To a/ZZ whom t may concern:

Be it known that I, JOHN A. BELL, a citizen of the United States, residing at Naperville, in the county of Du Page and State of Illinois, have invented certain new and useful Improvements in Vaginal Syringes; and I do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to a novel construction in a vaginal syringe, the object being to provide a device of this kind which can be easily inserted and operated by the patient herself and which is provided with a returnow to drain the liquid off and prevent the bed from being wetted; and it consists in the featuresof construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a vertical longitudinal section through a syringe constructed in accordance with my invention, taken on the line l l of Fig. 2, showing the liquid-nozzle and vagina-expanders in elevation. Fig. 2 is a similar horizontal section on the line 2 2 of'Fig. l. Fig. 3 is a transverse section on the line 3 3 of Fig. 2.

My device consists of a hollow conical shell A, closed at its larger end and open at its smaller end, the edge of the latter being eX- tended at one end to form a lip B, the object of which will be hereinafter more .fully described. Passing centrally through said shell A is a tube C, terminating at one end in a nozzle D, projecting from the open smaller end of said shell A. About midway between the ends of the tube flanges E and F are formed, which project outwardly at diametrically opposite points, said ianges E being of greater extent than said flanges F and engaging the edge of said shell A to prevent said nozzle D from being drawn into said shell. The inner end G of said tube C is screw-threaded and passes through a central opening in the end Wall of said shell A and receives a nut II,which bears against said end wall and serves to draw said iianges E in contact with the other end ot' said shell, thus holding said parts firmly in their relative positions. Beyond said screwthreaded portion said tube O is reduced in the usual manner to receive and retain the end of the rubber tube connecting said nozlzle with the source of supply of liquid. Rigidly secured to the said tube O and eXtending underneath the nozzle D is a wire frame I, which lies close against the tube O to a point below the flanges E, where it is bent downwardly at an incline and is widened. This downwardly-extending portion of said frame rests upon the end of the lip B and extends slightly below the saine. 'Ihence said frame is bent to extend upwardly toward the end of the nozzle D at a slight incline, and at the end of said nozzle said frame is bent upwardly and widened to form a loop J, projecting just in front of said nozzle D. The said frame I serves to depress the lower wall of the vagina and to prevent the end of the nozzle from striking the mouth of the womb and injecting the liquid into the uterus. The said flanges E and F are recessed or bifurcated to receive dilatinglevers K, pivotally secured to said nozzle between said flanges E and F. 'lhe said dilaters K consist of wires bent to form loops at their ends, the forward ends terminating flush with the end of the nozzle D and the rear ends projecting through slots L in said end wall of said shell A. The said forward ends of said levers K are also curved, so as to diverge between their ends, so that as said nozzle is inserted the vagina is partially dilated: The said levers K are normally held with their forward ends embracing said nozzle by means of springs M interposed between the tube O and the rear end portions of said levers.

In operation the nozzle is inserted into the vagina until the forward end of the shell A enters the mouth of same, thereby practically closing the mouth. The frame I serves to depress the lower wall of the vagina and said dilating-levers K to dilate or spread the side walls just inwardly of the mouth. W'hen so inserted the rear projecting ends of the levers K are pressed toward each other, thereby the liquid to reach all parts of the same, the dilaters covering only a minimum area. The liquid thus introduced will return to the shell A and is drainedfrom same by the return-dow nozzle N, extending from the lower rear end of said shell A, said nozzle being adapted to be connected with a flexible tube, if so defarther dilating the vagina and permitting 4 IOO - be made of a single piece or of two pieces, as

indicated in dotted lines, Fig. l, and may be readily taken apart to be cleaned.

I claim as my inventionl. In a vaginal syringe, the combination.

with a conical shell closed at its larger end and open at its smaller end, of a tube passing centrally through said shell and terminating in a nozzle projecting from the smaller open end of said shell, a frame rigidly secured to said nozzle and adapted to depress the lower wall of the vagina, dilating-levers pivotally secured to said nozzle between their ends and adapted at their forward ends to engage the side walls of the vagina, and at their rear ends projecting through slots in the rear wall of said shell, means for connecting said nozzle with a supply of liquid, and a returnflow nozzle mounted in the lower rear wall of said shell.

2. In a vaginal syringe, the combination with a hollow conical shell closed at its larger end and open at its smaller end, and provided at its smaller end with a projecting lip of a nozzle passing centrally through said shell and projecting from the said open end thereof, a wire frame rigidly mounted upon said nozzle and resting upon said lip, said frame being bent to form a loop projecting before the delivery end of said nozzle, dilating-levers pivotally mounted on said nozzle and proj ecting outwardly at each side of same, means for connecting said nozzle with a source of supply of liquid, and a return-flow nozzle mounted in the rear wall of said shell in aline'- ment with said lip.

3. In a vaginal syringe, the combination with a hollow conical shell closed at its larger end and open atits smaller end, and provided at its smaller end with a projecting lip of 'a nozzle passing centrally through said shell and projecting from the said open end thereof, a wire frame rigidly mounted upon said nozzle and resting upon said lip, said frame being bent to form a loop projecting before the delivery end of said nozzle, dilating-levers pivotally mounted on said nozzle and projecting outwardly at each side of same, the forward end portions of said levers forming loops curved between their ends and the rear end portions diverging and passing through slots in the rear wall of said shell, springs interposed between the rear end portions of said levers and said nozzle for holding the forward ends of said levers normally at the inner limits of their movement, means for yconnecting said nozzle with a source of supin presence of two witnesses.
